An electrode arrangement is provided having an electrode line which has a closed casing for sealing off its interior relative to the surrounding area. At its distal end, electrically conducting surface regions serve as electrodes. A fixing mechanism anchors the distal end in a body tissue, in particular heart tissue and is adapted to be separable from the rest of the electrode line in such a way that the rest of the electrode line is also closed at its distal end when the fixing mechanism is separated off. The interior of the electrode line is sealed off relative to the surrounding area even when the fixing element is separated off. The electrode arrangement is characterized by a mechanism for separating off the fixing mechanism, which is adapted to effect separation by virtue of forces acting axially within the electrode line.

Break-away extractable lead

The invention concerns an implantable defibrillator ( ) comprising a chargeable voltage source ( ) and a pulse generator ( ) which is formed from a voltage multiplier ( ) and a capacitor ( ) chargeable to the defibrillation voltage. Provided between the capacitor ( ) and the voltage source ( ) is a line connection ( ) by way of which electrical energy which has not been consumed or which is not required for the tissue stimulation procedure can be returned from the capacitor to the voltage source.
